The shank 2 5 is pivotally connected to theangularlever 26 by means of which the latching member is drawn back, thespring24 beingcompressed. A link 28 is mounted upon the pivot member l5and bolt 21 and is locatedbetween the armsof the lever 13. Anenlargement upon the link 28, a tapered washer, or other equivalentmeans surrounds the bolt 21 and is'arranged to cooperate with thetapered or wedge shaped head 23-of the latching member. It willtherefore be apparent that when the lever 26 is released the spring 24will force the wedgeshaped head 23 to press the links 18 outwardlyagainst the arms of the lever 13. 'Fiberor other suitable washerssurround the bolt 21 and are located between the links 18 and betweenone of these and member 28. Therefore, members 18 and lever 13 areprevented from having. move 'ment relative to each other when head 23 ispushed. forwardly by spring .24. Thus, lever 13 is locked in anyadjusted position and holds the plunger .4 where it may happen to be. .i

By pressing lever 26 toward the end 30 of lever 13 and then raising thislever, the.

plunger 4 is forced downwardly or, rather, the lower arm of frame 1 isra1sed, causing compression of spring 31, shown in dotted outline inFigs. 1 and 7. lVhen proper com-- pression is reached, the handle 26 isreleased and the head 23 is-forced inwardly tocause the latching orgrasping of the device and the holding of spring-31 compressed The frame1 may be made integral, if desirecl,or, if preferred, it maybe madeintwo sections provided with slots 32 through which pass the bolts 33which are threaded into-one of these members so as to permit relativesliding of one relative to the other.

When'proper adjustment of these parts is secured, the bolts 33 areturned in so asto tightly hold these two partsof the frame,

relatively to each other;

Adjustment of the distance-betweenthe end 5 of plunger 4 and the springholder 2 may be accomplished in other ways than .by

sliding the two arms of the frame 1 relative to'each other. As a matterof fact, the slots "32and bolts 33 may be dispeu sed. with en-v tirely,if desired. One of the means for making theadjustments referred to isthe screw 8 which may be turned out so that it does not engage theplunger 4 andthis plunger may then be adjusted longitudinally throughthe head 3 and collar 7, whereupon the screw or bolt 8 will again. beturned in to secure theplunger 4*against movement 7 7 relative to thecollar 7. It will therefore be 22in the head is indicated in seen fromthis that a considerable range of adjustment may behad in this way.Also, a different range of adjustment may be had by reversing the links11 and placing the collar 7 on the upper portion of the plunger 4, asillustrated in Fig. 3. The two arrangements can be compared by comparingFigs. 1 and 3 which showsame. Fig. 7 shows therelative arrangement ofthe parts when the handle 30 is raised andtheplunger 4 de-.

pressed, the collar 7 being below the head 3, as in Fig. 1.

Fig. 7 also illustrates the use of this device in compressing aspringpreparatory to installing same man automob1le. To accomplish this,the parts of the device are arranged as in Fig. 1 and the pin 6 isremoved from the;

plunger 4. A- spring 31 is then mounted upon the upper'end of theplunger 4 and the pin 6 is replaced as illustrated. The handle may nowbe raised and this will cause longitudinal motion of the plunger 4 andcompression of the spring 31, as indicated in .Fig. 7 A spring holdermay then be placed about the spring 31 to hold the same compressed. Ifthe lever 13 is now lowered, it'causes the plunger to be raised towardthe position shown in Fig. 1 and the pin 6 may be withdrawn, thuspermitting the spring to be removed from the plunger 4 and inserted inits normal place in the engine.

The action of the clutch may be varied by tightening or loosening thenut of the bolt 21 which draws the parts closer together or permits themto springfarther apart. It will thereforebe evident that when such anadjustment ismade the latching means will be 4 be apparent that it isnotnecessary to press the handle 26 down fully so as to Completelyrelease the latching or gripping means and I that if this is onlypartially released, the plunger 4 and jaws 2 will approach as slowly asmay be desired, the speed being regulated by the pressure upon lever 26.

It is of course understood that the specific description of structureset forth above may be departed from without departing from the spiritof this invention as set forth in this specification and theappendedclaims.

Having now described my invention, I

claim 1. In a valvespring compressor, a frame 1 having a head extendingtransversely to one side of the frame andin the planethereof,

ing means capable of holding the leverin position of adjustmentzthereof.

7 2. In a valve spring compressor, a

alever for reciprocating said plunger, and holding means for holding thelever in various positions of adjustment, said holding means comprisingan elongated, fiat, longiber pivotally connected tothe frame, a leverpivotally connected to the frame and connected tothe plunger to causeactuation theretudinally slotted member carried by the frame, anengagingelement carried by the lever and; adapted to" cause frictionalgrip pingof the slotted member at any point desired, and resilient means to''actuate the holding'element into position to cause such gripping. W

3. structure cfor the purpose indicated comprising a frame havinga'n armcarrying a longitudinally aperturedhead, a plunger sli'dable in the,aperture'in said head, a lever I .--pivotally mounteduonsaid'frame'andconnected to saidplunger to slide same through said aperture, alaminated slotted link connected to said irameandsaid lever, means onsaid lever for immovably connecting the lever i to the link so that theplunger willloe held, against sliding in said aperture',-and nonvmetallic friction means between thelever and the slotted link to enablethe operator to sloW- ly release spring tension.

4. In a structure r'or the purpose indicated, a frame comprising a headhaving a plunger slidable therethrough, a slotted holding mem-v V ofthrough the frame, and clamping means carried by the lever andfritcionallyengage-z able with the slotted holding member, with varyingdegrees of pressure, tocmeasurably 1 retard the movement of thelever andplunger, said clamping means serving tojho1d'the lever and plunger inany desired positionof adjustment.
